Weather peril exposure
SOMERSET PLANT is a 117 MW biomass power plant in Suffolk County, MA, operated by SAPPI FINE PAPER NORTH AMERICA-SOMERSET, commissioned in 1976. Suffolk County carries low modeled catastrophe exposure in the FEMA National Risk Index, scoring 1.6 of 5 at the 15th national percentile. Lightning is the leading peril, rated Very High by FEMA at the 81st percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to a biomass plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
